Currently reentry of USA Space Shuttles and Command Module of Lunar Ships burns a great deal of fuel to reduce reentry speed because the temperatures are too high for atmospheric braking by conventional fiber parachutes. Recently high-temperature fiber and whiskers have been produced which could be employed in a new control rectangle parachute to create the negative lift force required. Though it is not large, a light parachute decreases Shuttle speed from 8 km/s (Shuttle) and 11 km/s (Apollo...

Author offers a new method for delivery of an asteroid to Earth which is many times cheaper than conventional methods. In this method, kinetic energy is used not only for the braking apparatus but is also used to charge the apparatus energy storage. A small control parachute using the Earth atmosphere for braking the asteroid without high heating, delivers the asteroid to a given point and avoids damaging impact to Earth. Though it is not large, a light parachute decreases asteroid speed from...

Authors offer the new method for deliver the asteroid to Earth. That method is cheaper in a lot of times than a conventional method. In our method for braking apparatus and asteroid are used the kinetic energy of apparatus. This energy is used also for charging the apparatus energy storage. The small control parachute allows multiple using the Earth atmosphere for the braking the asteroid without high heating, deliver the asteroid in given point and to avoid the asteroid impact to Earth. In...
